Various Types of Water Heaters | Roto-Rooter Blog

When it's time to buy a new water heater you have several different options. The specific requirements of your business or household will determine which water heater is right for you.The following information from a Roto-Rooter plumber is designed to help you choose the best water heater for your situation.

Different Types of Water Heaters

There are five different types of water heaters. A brief summary of the elements found in each type is listed below:

Conventional Units with a Storage Tank

The most common water heater is the tank-filled type. You can get either natural gas or electric units. This style contains several gallons of water that is always kept hot. When you turn on the hot water taps, the water travels from the tank to the faucet.The water that comes out of the faucet is cool at first. This is because the hot water cools down while it sits in the pipes until the tap is turned on.The plumbing requirements for these models are fairly standard and found in most homes. However, conventional units are expensive to operate. The cost of heating the water can amount to about 30 percent of your energy bill.

Tankless or On-Demand Systems

Tankless water heaters use much less energy than the conventional appliances. As the name implies, there is no water storage tank with these units. Instead, a heating unit heats up the water as it passes through the system. Therefore, when you turn on the tap you get hot water immediately.On-demand systems come in a wide variety of sizes: small enough to fit underneath a sink or large enough to provide hot water for an entire house. They work best in small households where there is little simultaneous demand for water.Most plumbers can install and service tankless water heaters.

Other Water Heaters

There are three other water heaters that are less common than the two listed above. They include the following:

  • Solar water heaters
  • Heat pump water heaters
  • Indirect water heaters

These three systems are more energy efficient than the conventional water heater. Therefore, they are friendly to the environment. However, they do have special plumbing and/or construction requirements that you should take into consideration when deciding whether or not to switch to one of these systems.


Criteria for Selecting a Water Heater

When selecting the right kind of water heater you should consider the following:

  • Energy sources that are readily available
  • Cost to operate
  • Size needed for your family
  • Space available
  • Energy efficiency
  • Installation requirements
